I've been working with a dead Sony KV-1913 for a while... apparently, all of a sudden, it started making all sorts of buzzing noises, and just failed to work. From a friend's advice, I checked capacitors, replaced one, and at the same time, replaced a blown 1.5A fuse (like it just popped of old age... no blackening around the glass). So all is well, I go to power it up, and apparently, something else isn't quite right--it blew its main 5A fuse pretty fast. Tried bringing it up in series with a light bulb (with the degauss coil removed), and the light bulb is almost at full brightness, probably indicating a short, though resistors and capacitors seem to check out fine in the power supply section. Also, when powered on with the light bulb load, there is a high-pitched whine (perhaps the horizontal deflection?) Transistors were also checked, and I didn't see any giving a dead short, but I might be missing some...
Pretty much, if this is the flyback giving me headaches, I think it's time to retire this TV and take it out to the recycling center, but if it's possible it is another part that I haven't checked, or perhaps missed, help would be appreciated. I've tried running through all of the possible scenarios on the SER FAQ, and just haven't made it any progress with any of those possibilities...
Perhaps one source of this short, the only place on the board I noticed blackening was in an insulated clear tube--I think it's insulating a capacitor in an odd spot beside all the connectors (to the power switch, degauss, etc.) and near the main filter capacitor. It seems to be charging up fine, but that's the only spot I see any blackening at all.
